# Inert recorder is similar to a null object in the sense, that in response to
# almost all messages it returns self. But in addition, it records received
# messages along with their arguments and blocks (if given). Recoded messages
# are available via #recorded_messages reader, aliased #ρ (small Greek rho).
# Inert recorder does not require any arguments for initalization, but if they
# are supplied, they are silently recoded into @init_args (for arguments) and
# @init_block (for block, if given) instance variables, exposed via standard
# readers.
